5004CEM Lab 4 Creating a Bootloader
In this lab, you should complete the Basic Tasks and the Advanced Tasks.
I recommend you explore the helloWorld.asm and helloWorld_loop.am code that is provided in Session4 on the server and on AULA. To complete the Advanced Tasks, you will need to use full or parts of registers. As we are using 16-Bit NASM, the registers you can use are limited to 16-bits such as CX and DX and 8-bit sections of these registers such as CL, CH, DL, DH, as well registers such as AL.
See the ‘Getting Started with Lab 4’ video on AULA to give you additional information on completing this lab.
If you have any additional questions on this lab or any other labs please do not hesitate to ask your tutor and/or email me on ab0487@coventry.ac.uk.
